It's not that we've advanced more in the last 150 years. It's that it took us 10,000 years to learn our lessons.
Just as it takes us 10-12 years of compulsory schooling to then be able to talk, spell, read and write to a decent degree, use the remote control, catch the public transports, talk and think like an adult etc.
Then all of a sudden, you're able to pick up things faster e.g. how to drive a car, install your own apps on iphones without technical support, understand and balance your personal finances, fill out your taxes etc etc.
But there is still a whole lot you do not know and have to take extra learning on - which some of us never do - e.g. fly a plane, do heart surgery, design a house, learn another language, write a book, learn to exercise, learn to eat sensibly, be kind, be open-minded, be a better parent (getting to do it right second time round through your grandchildren), do rocket science etc etc.
For all we know, we're still in the embryonic stage. 150 years from now, someone might ask why have humans advanced more in the last 5 years than the previous 10,150 years?
